Do you regret choosing your power adder?

[Forestlump]

What s/c makes more power throughout the whole powerband?

What S/c is lightest and allows the car to perform the best on a circuit?

I don't think that is the o/p use for his car. So then an F1 car is what we all need on the circuit.

The fast mini coopers throw that tiny Heaton in the garbage and go turbo

We're talking about fucking Mini Coopers now. Ugh.

The fast stangs go turbo, wheres your turbo?

I wish!

How could you even get an air to air system working with a PD supercharger?

aside from a lot of extra piping, it's really no different than what sits on the exhaust side of a Centri or turbo. Both systems frankly should go the other way and super-cool the intake air. I'm just gonna hand-wave away the water vapor->ice issue. Because I ain't no enginear.

can you get me the list of the fastest mustangs at "the circuit" and what power adders they are using? Are they Vortech, Procharger, or ESS?

The mighty GTD is going to be using a PD supercharger btw

that WING is worth 100hp all by itself. You know it. I know it. We don't need no stinkin' wind tunnel analysis and data pickups.

• Specific heat capacity (Cp ) air at 0°C and 1 bara: 1.006 kJ/kgK = 0.24028 Btu(IT)/(lbm °F) or kcal/(kg K)
• Specific heat capacity (Cv ) air at 0°C and 1 bara: 0.7171 kJ/kgK = 0.17128 Btu(IT)/(lbm °F) or kcal/(kg K)
• Thermal conductivity at 0°C and 1 bara: 24.35 mW/(m K) = 0.02094 kcal(IT)/(h m K) = 0.01407 Btu(IT)/(h ft °F)

• Specific heat (Cp ) water (at 15°C/60°F): 4.187 kJ/kgK = 1.001 Btu(IT)/(lbm °F) or kcal/(kg K)

This is why people use water. The 'to-air' heat shedding of the cold side is ~same since the size of the radiator is ~same and made of the same materials and fin structure etc.

Water is simply a buffer that can absorb 4x as many J or btu than air, till it reaches saturation and is then gated by the ability of the cold side to shed the heat. But on a 10 second pull nobody cares that it takes 2 hours to cool the water system down before it's next run. It absorbed the heat out fo the intake charge and thats what matters.

Exactly! infact it's slightly worse as energy will only flow one direction from hot to cold.

The smaller the delta T is, as it heads toward equilibrium there's no more energy exchange so you will have less and less cooling.

Air to water to air delta T of 20
Ambient 20
water 40
boost temp 60

Air to Air cooler delta T of 20 degrees
Ambient 20
Boost temp 40


and if we went air to water to air to water to air again, just for a laugh, we would get
Ambient 20
water 40
air 60
water 80
boost temp 100

All with the same cooling efficiency thats the full story of cooling with water. Something a few of you are missing.

This thread continues to deliver!! I forgot to answer the OPs question, no I do not.

From a pure intellectual level in this thread, @engineermike is likely light years ahead of most everyone in here regarding the review and understanding of data logs and mechanics that drive them.

I’d like to remind everyone else that it’s okay to be proud of what you spent your money on. But that doesn’t mean it’s the best thing out there.

@engineermike lives up to the username. Ive found if hes talking about something its probably because he has done some research and testing and probably knows a good amount about it.

If I am going to argue with him I better be bringing some good evidence.

All hail Engineermike then and his physics defying wipple Mustang that can do everything better than yours including make tea.

There you go folks, if you want to FI your Mustang and not be told you did it wrong, speak to mike and his entourage of loyal fans!

A few data logs and a car forum full of experts has deemed the pinnacle of FI engineering as Whipple.

I'm off to buy Whipple shares!

You must be a politician as well!

Since getting a s550 just always wanted a PD blower. Bought a10 3.15 gear 21 gt and kept deciding between a roush or whipple due to being a fun daily blower.

Have been reading that a lot of people say a centrifugal is better for an auto due to the powerband and shift points.

Did you go pd and wish you went centri?

just assumed that a turbo wouldn’t be the ideal daily setup.

Turbo has no real reason to be bad for daily, turbos are in general most effecient and least strain per boost psi on a motor. The problem with turbos is oil lines, coolant lines, tight clearances and heat soaking from the clearances, and of course most expensive system for boost

im happy with centri, i would love a whipple myself but i street exclusively, and drive year round in ny, snow, rain, or sunshine. So i need all seasons, i really dont want to use a slick as that takes away all rain and snow and even cold temp usage. For me, for now 265 all seasons with manual non pp seems to hold the pump gas power well enough, later on e85 il swap to a 315 all season and see if its possible, if not then a 315 summer tire.
Whipples biggest issue to me is the need for extensive tire and suspension mods to allow for putting the power down, otherwise its half throttle everywhere

Centri is great for auto as it combines 10 gears to maximize centri power band, but the whipple does a good job with it as well, to my knowledge the centri does better with heat so thats always an advantage if the auto keeps you in powerband

Between a whipple and roush, i would always go whipple for effeciency, the only good reason for a roush is for warranty reasons if the dealer installs and keeps warranty
